Embodiment

[0059] Such as figure 1 As shown, the real-time monitoring system of urban water supply pipe network is mainly composed of monitoring center, communication network and on-site monitoring terminal RTU. Specifically, it can be subdivided into measurement and control equipment (sensor, pump station, sluice and other control execution equipment), on-site measurement and control module, communication gateway, remote GPRS-DTU (Data Transfer Unit), monitoring center, and information service terminal. The field monitoring terminal RTU includes field measurement and control module, short-range communication network, and remote GPRS-DTU. Based on 3C+S (Computer, Communication, Control, Sensor) technology, it adopts a multi-level system structure of equipment layer—control layer—dispatch layer—information layer, and a unified technology platform (unified data protocol, communication network, database sharing), Through different network (Internet, mobile phone SMS GSM, telephone network P...

Abstract

The invention discloses an optimized layout method for pressure monitoring points of an urban water supply pipe network. The method comprises the steps that S1, basic data of the urban water supply pipe network is acquired, EPANETH software is utilized to calculate hydraulic adjustment of the water supply pipe network, and a hydraulic model of the urban water supply pipe network is constructed; S2, a pressure difference matrix, a shortest distance matrix and a water volume influence fuzzy similar matrix are solved according to the hydraulic model of the urban water supply pipe network, and constraint conditions of an optimized layout model of the pressure monitoring points of the urban water supply pipe network are determined; S3, a model objective function is determined, and the optimized layout model of the pressure monitoring points of the urban water supply pipe network is constructed; and S4, a particle swarm algorithm is utilized to solve the optimized layout model of the pressure monitoring points of the urban water supply pipe network, and an optimal pressure monitoring point and monitoring areas of all the pressure monitoring points are determined. The method has the advantages of being simple in principle, easy to realize and high in efficiency and meets the requirements for representativeness, comparability and feasibility of point distribution.

Description

Technical field [0001] The invention relates to the technical field of optimized arrangement of pressure monitoring points for urban water supply pipe networks, and in particular to a method for optimizing the arrangement of monitoring points combining pressure relevance and water volume influence fuzzy similarity matrix. Background technique [0002] With the continuous expansion of the scale of urban water use and the growth of the service life of the pipe network, the waste of water resources is becoming more and more serious. Relying on the original traditional methods to monitor and control the water supply network is far from being able to meet the current needs. With the rapid development of science and technology today, comprehensive, effective, real-time, and accurate monitoring of the urban water supply network has become a major issue for the management department. [0003] The water pressure of the urban water supply pipe network, as an important parameter of the opera...
